Emerson DeltaV™ SQ Controller Scalable Controller Product Description

Product Description

The SQ controller executes control logic based on process signals from the I/O subsystem.

The SQ Controller executes control logic based on process signals from the I/O subsystem

and provides communication with the rest of the DeltaV control system for operator interaction and data collection.

Each controller node can be installed as a simplex or redundant node.

Each controller node can be installed as a stand-alone or redundant node.

Each controller node can be installed as a standalone or redundant node.

The controller is connected to an I/O carrier mounted on the right side of the controller carrier.

Up to 8 carriers can be connected to the local bus I/O.

Each carrier has 8 I/O cards for a total of 64 legacy I/O cards.

In addition to the 8 local input/output carriers, each controller can be connected to an additional 16 I/O carriers.

Each controller can also communicate with an additional 16 remote I/O units that carry legacy card-based inputs/outputs.

In addition to traditional I/O cards, the local bus supports Feldbus technologies including Foundation Feldbus, Proffbus DP, DeviceNet and AS-i protocols.

The I/O subsystem also supports serial interface cards and Ethernet I/O interfaces.

The SQ controller also supports CHARM and WirelessHART I/O cards.

The CHARM I/O card (CIOC) connects through the controller's redundant Ethernet ports to provide a highly distributed and flexible I/O solution called an e-solution.

solution. Up to 16 CIOCs can be connected to a single controller, each providing up to 96 individually controllable signal types.

SQ controller capacity limits may vary depending on the specific application, number of CHARM I/O signals, and control performance requirements.

Enhanced Memory Handling and Hardware Alarms, Indexed to Cover Capacity and Memory

Enhanced memory handling and hardware alarms covering capacity and memory have been added to the SQ controller's diagnostic information through indexing.

The WirelessHART I/O Card (WIOC) provides redundant communications for up to 100 WirelessHART devices, ensuring high availability and reliability of wireless data.

Up to 16 WirelessHART I/O cards can be connected to a single controller, each providing up to 100 signals.

The controller automatically schedules control modules based on the assigned scan rate.

This allows each control function to be dynamically optimized for the process.

Module scan times can be set as fast as 100 milliseconds and as slow as 60 seconds.

The number of control modules that can be assigned to the controller depends on the complexity and scan rate of each module, as well as the available CPU and memory.

The SQ controller is suitable for small to medium sized applications with up to 750 independent I/O signals.

Designed for harsh environments, the SQ controller is rated for G3 corrosive environments and has an operating temperature range of -40 to 70°C.

It is ideal for use close to process equipment.

It is ideal for remote installations close to process equipment.

For traditional installations using a central dispatch cabinet, the CHARM I/O card can be installed in a standard I/O cabinet that provides electronic dispatch capabilities.

The CHARM I/O card can also be used in highly distributed I/O applications.
